Process Scheduling and Program Monitoring on Transputers

Parallel program monitoring is a key to success in parallel program development. We have developed a novel approach, called the logical clock approach , for the highly transparent monitoring of parallel programs. To apply the logical clock approach in monitoring occam programs on transputer-based systems , we rst study the (micro-coded) process scheduler of the transputer, and then demonstrate how the information on process scheduling can be employed for correctly updating logical clocks and controlling inter-process communication in logical clock monitoring.
